SPC563M64
Overview
Doc ID 14642 Rev 6
Event-triggered microengine:
Fixed-length instruction execution in two-system-clock microcycle
14 KB of code memory (SCM)
3 KB of parameter (data) RAM (SPRAM)
Parallel execution of data memory, ALU, channel control and flow control sub-
instructions in selected combinations
32-bit microengine registers and 24-bit wide ALU, with 1 microcycle addition and
subtraction, absolute value, bitwise logical operations on 24-bit, 16-bit, or byte
operands, single-bit manipulation, shift operations, sign extension and conditional
execution
Additional 24-bit Multiply/MAC/Divide unit which supports all signed/unsigned
Multiply/MAC combinations, and unsigned 24-bit divide. The MAC/Divide unit
works in parallel with the regular microcode commands
Resource sharing features support channel use of common channel registers, memory
and microengine time:
Hardware scheduler works as a “task management” unit, dispatching event
service routines by predefined, host-configured priority
Automatic channel context switch when a “task switch” occurs, i.e., one function
thread ends and another begins to service a request from other channel: channel-
specific registers, flags and parameter base address are automatically loaded for
the next serviced channel
SPRAM shared between host CPU and eTPU2, supporting communication either
between channels and host or inter-channel
Dual-parameter coherency hardware support allows atomic access to two
parameters by host
Test and development support features:
Nexus Class 1 debug, supporting single-step execution, arbitrary microinstruction
execution, hardware breakpoints and watchpoints on several conditions
Software breakpoints
SCM continuous signature-check built-in self test (MISC - multiple input signature
calculator), runs concurrently with eTPU2 normal operation
For SPC563Mxx, the eTPU2 has been further enhanced with these features:
System enhancements
Timebases and channels are run at full system clock speed
Software watchdog with programmable timeout
Real-time performance information
Channel enhancements
Programmable channel mode allows customization of channel function
Channels 1 and 2 can optionally drive angle clock hardware
Programming enhancements
Engine relative addressing mode
More flexibility in requesting DMA and interrupt service
Channel flags can be tested
